42 Claims.

This invention relates to machines for applying reinforcing material to insoles such, for Vexample, as are used in the making of welted shoes, and particularly to machines for applying a strip of fabric such as duck or canvas to the inner face of the rib and to the body of the insole adjacent to the rib. Machines of this type are disclosed in Letters Patent of the United States No. 2,242,248 and No. 2,296,847, granted May 20, 1941, and September 29, 1942, respectively, on applications of Stanley M. Griswold and Russell K. Nash.

Objects of this invention are to provide a machine of this type which will be more eiiicient, more durable and better adapted for quantity production without, however, sacricing any of the advantages of said priormachines.

As inV said prior machines, the illustrated machine comprises a lower feed roll to engage the unribbed face of an insole, an upper feed roll to engage the feather of the insole, said rolls being separated to receive the work and pressed together to cause the work to be fed, and an applying roll movable into and out of operative position with respect to the ribbed face of the insole and acting to apply a cemented strip to the inner face of the rib and to the adjacent body of the insole. As heretofore, manually operated means, for example a treadle, is utilized to press the feed rolls together and to move the applying roll into operative position.

A feature of the present invention consists in providing separate and adjustable yielding devices through which the feed roll and the applying roll are operated. Thus, the pressure of thev feed rolls upon the work may be controlled independently of the pressure of the applying roll upon the strip being applied and greater pressure exerted upon the feed roll than upon the applying roll.

Another feature of the invention consists in soA mounting and operating the feed rolls that the space between them is unobstructed and the machine is thereby adapted for operation on insoles having portions projecting abnormally far beyond the rib, as in insoles having a shanksupporting extension commonly known as a cookie A still further feature of the invention relates to the strip-applying device or applying roll and consists in making one part of the applying device yieldable with respect to another part of it so that engagement of one part with a thick portion of the insole will not prevent pressure of another part on a thinner .portion of the insole. As illustrated, the part of the applying device which engages the strip over a thinner portion of the insole, for example over the inside channel, is mounted to yield upwardly with respect to the remainder of the device which engages the strip over a portion of the insole of full thickness. Provision is made for setting the yieldable portion of the device at different distances below the remainder of the device. As illustrated, the applying device comprises a plurality of spurred disks to engage the strip over the portion of the insole of full thickness and another spurred disk to engage the strip over the channel of the insole, said last-named disk being mounted upon a slide having a surface formed flush with the disk to rub the strip into the channel and another surface formed to rub a portion of the strip against the inner face of the rib, said slide and the disk mounted thereon being yieldable to operate uniformly in channelsof dilferent depth.

These and other features of the invention, including various convenient adjustments and novel combinations and' arrangements of parts, will be more fully understood from the following description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

Fig. 13 is la similar View showing both sides so reinforced.

Referring to Fig. l of the drawings, the machine comprises a triangular base 2i) and a vertical column 22 the upper end of which is bored to receive a hollow neck 2li which is adjustably held in the column 22 by clamping bolts 26. To the neck 2li is secured a box or casing 28 on which a head casting 33 is mounted. The head St is provided vwith bushed bearings S2 for a shaft '3d which carries the lower feed roll 35 at one end and a driving pulley 38 at the other. Power is supplied to the pulley through a belt ld from a countershaft pulley carrying a disk 4d which may, at will, be pressed toward the rear face of a pulley it driven by a belt @a from a motor l, there being between the disk M and the pulley 46 a loose friction disk 52 of leather and a spring (not shown) to separate the pulley and the disk 44.

A frame or yoke 54 (Fig. 3) is mounted for movement about a horizontal xis directly over the rear bearing 32 by'means of pins 55 having conical ends arranged to enter conical recesses on opposite sides of the yoke, the pins being held in place by draw bolts 58 (Fig. 7). Front and rear bearings |55, 62 are provided in the yoke 5d for a shaft 64 which carries an upperfeed roll E55. rhe upper feed roll is driven by a, gear 68 pinned to the shaft 64 and meshing with a gear u pinned to the shaft 34. The arrangement is such that when the yoke 54 is swung about the center 55 to cause the feed roll @t to engage the feather of the insole the shaft M will be substantially parallel to the shaft 3d and hence the teethof the gears (i8, 'Hl will be parallel to each other and there will be a free space between the bearings 32 and Sil high enough. to permit passage through it of a lateral projection, such as a cookie, on the insole.

Associated with the upper feed roll t5. is an outside guide 'i2 (Fig. 6) the rear portionof whichyhas parallel sides which engage a corresponding vertical recess 14 formed in a block l. The block 'l5 has parallel sides which engage a corresponding horizontal groove in the yoke 5d. .A screw dil passing through a horizontal slot in the block 16 and threaded in the yoke 5ft serves adjustably to secure the block 'it to the yoke, and a screw 8% passing through an enlarged hole in the guide l2, through a slot in the block and threaded into the yoke 54, serves adjustably to hold the guide l2 in vertically .adjusted position relatively to the block 16 and to hold both the guide and the block to the yoke 5dr. The .guide '|21 has adjacent to the upperI feed roll E6 (Fig. 8) a curved face corresponding to the curvature of the roll and substantially in contact therewith. The above-described heightwise and horizontal adjustments of the guide 'i2 enable it to be locatedwith respect to the feed roll 65 properly to engage the outer face of the rib and the feather of the insole, thus to assist in guiding the insole past the feed roll.

The mechanism for moving the upper feed roll 66 toward and from the lower' feed roll St comprises a rockshaft 62 journaled in the frame 3% (Fig. 3) and having fixed thereon aV lug 8.4 through the outer end of Vwhichy is threaded a screw 85 which is locked in adjusted position by a nut 8B.v Freely pivoted onthe rockshaft 32 is a member 9|) (Fig. 10)v which is held from rear-A ward movement on the shaft G2 by a collar 92 fixed to the shaft (Fig. 3). A .plunger 9d (Fig. I

) extends through the member` Si! which is counterbored to receive a collar 96 fixed to the plunger 94 and is further counterbored and threaded at 98 to receive a threaded sleeve |60 through which the plunger 95 freely passes. Between the collar 9% and the sleeve l is a compression spring m2 the initial tension of which may be varied by turning the sleeve which may be locked in adjusted position by tightening a lock nut llll threaded on the sleeve. The yoke 5f! carrying the upper feed roll 66 is held normally in raised position by a spring lil (Fig. 3) fastened at its lower end to the yoke 56| and at its upper end to a, pin its on the frame 30. The yoke is connected by a ball-ended link ||l to the member 9B (Fig. .10), the upper ball of the link being held in the member by a slotted plate l2 and the lower end being held in the yoke 54 by asimilar plate lid. The ball-ended link Hi! permits longitudinal movement of the shaft 82 for a purpose later explained. Turning of the shaft 82 causes the screw 86, after a period of lost motion determined by the setti-ng yof the screw, to engage the plunger Se and move the member S with the shaft 82, thus pressing downwardly on the link i iii and causing the yoke 51% and the upper feed roll to swing about the center 55, overcoming the spring |li5. When the work is in the machine and hence approaching movement of the rolls is obstructed, the spring |92 will yield and the pressure of the roll 66 upon the work will be determined by the initial tension to which the spring was set by adjustment of the sleeve Hill. When no work is in the machine, the rolls are prevented from engaging each other by a stop screw l i6 threaded through a portion of the frame E@ and held in adjusted position by a lock nut i8. After a predetermined movement of the shaft 82, a lug |2E3 on the member 9|) engages the screw H5 and prevents further movement of the yoke and feed roll; further rotation of the shaft 82 by compression of the spring |62, however, is permitted.

To the rockshaft 82 is pinned a lever one arm |22 of which extends to the left (Fig. 8) and is pivoted at |24 to a rod |25. The rod |2| (Fig. 2) has a collar l2 at its lower end which can slide freely in a sleeve E3B which is secured to a rod |32. An apertured plug i3d through which the rod |28 passes is threaded into the upper end of the sleeve lli-i! and has threaded thereon a lock nut |36. Between the plug |34 and the collar |28 is a compression spring |33 the initial tension of which may be adjusted by turning the plug |34. The rod |32 is urged upwardly by a tension spring ifi- (Fig, l.) connected between a collar on the rod and a pin on the machine frame. The rod E32 passes through a sleeve |132 which is held against depression by a. clampcollar M3. The sleeve |42 is pivoted at ldd to the long arm |46 of a lever journaled at |138 in the column 22. Forwardly of .the fulcrum M3 a shortJ arm I-5 of the lever is. pivoted to a rearwardly inclined link |52 which in turn is pivotedat |55 to an upwardly extending, rearwardly inclined arm |56 of a bell-crank` lever, the other arm |53 of which is formed'as an operating treadle f6.8. The bellcrank tread-.le leverY it, i is pivoted to the base at |62 and depression of the treadle will cause straightening of the toggle formed` by the arm |55 and the link 52 to cause` downward movement of the lever arm Md and, through the rods 32, l, to cause counterclockwise movement of the shaft S2. The springi should so set that it will not be :substantially .compressed until the springv itihasyielded Depression of the treadle |68 to bring the rolls 36, 66 together causes rotation of the rolls by power. On the rod |32 (Fig. l) is a collar |64 which, as the rod is depressed, engages a spring |66 encircling the rod and resting on a bifurcated arm'68 `of a bell-crank lever pvoted at |18 the other arm |12 of which engages the hub of the pulley 42. The collar |64 is initially considerably above the spring |66 so that only during the later portion of the depression of the treadle will the collar engage the spring and rock the bellcrank lever` |68, |12 to press the friction disk 52 against the face of the motor-driven pulley 46, thus causing the feed rolls to be driven. When the treadle is released the disk 44 engages a braking pad |13 adjustably xed on the machine and is quickly brought to rest.

Counterclockwise movement of the shaft 82 to bring the feed rolls together also moves the tapeapplying roll into operative position. As shown in Fig, 11, a casting |14 is xed to the front end of the rockshaft 82 and is bored to receive an electric heating unit |16. On the left-hand end of the casting |14 (Fig. 1l) is mounted a stripapplying device or applying roll indicated generally by the numeral |18 and shown in detail in Figs. 4 and 5. A body member or carrier |69 secured by screws |82 to the casting |14 carries a fixed stud |64 on which is mounted a plurality of spurred disks or rolls |86. In the body member |88 is formed a guideway which is vertical, as shown in 4, and receives a slide |68. On the slide |88 is formed a face |96 which engages one marginal portion of the strip and rubs it against the inner face of' the rib of the insole. Opposite the face |96 the slide |88 has formed thereon a stud |92 upon which is mounted for free rotation another spurred disk or roll |94. The disk |94 therefore is movable with the slide |83 relatively t9 the disks or rolls |86. The slide |68 is bored at |86 to receive a compression spring |98 the upper end of which abuts an angle plate 269 secured by screws 292 to the body member |89. Downward movement of the slide |88 in response to pressure of the spring |96 is limited (Fig. by a ledge 284 formed on a plate 286 having slots through which cap screws 288 pass and are threaded into the body member |80. By loosening the screws 298 the plate 296 may be adjusted to vary the amount the disk |94 is held by the spring |66 out of axial alinement with the disks |86. The periphery of the disk |94 is substantially flush with the lower end of the slide |88. The end face of the slide |88 and the periphery of the disk |94 engage the portion of the strip which is laid in the channel of the insole while the disks |86 lay the inner marginal pertion of the strip against the body of the insole. Since the depth of the channel may Vary somewhat, not only in different insoles but even in the same insole, it is desirable to have the disk |94 yield heightwise of the insole rib so that all the disks will constantly engage the work notwithstanding variations in the depth of the channel. rlhis is accomplished by the construction shown.

Also mounted on the casting |14 are a guide 2|!) for the strip S, a tensioning device 2|2 for the strip, a finger 2|4 for pressing the strip against the applying roll |18 as the roll moves into operative position, an inside guide 2|6 mounted on the linger 2|4, a strip guide 2|8 adjacent to the applying roll which bends downwardly one marginal portion S of the strip, and

a member forming part of the guide 2|8 and` having an edge 226` about which thewmarginal portion S of the strip is bent to bring it into a position parallel to the inner face of the rib, all of which parts, except as noted below, are constructed and operated substantially as explained in the above-mentioned patents. In the present construction, the finger 2l4 (Fig. 1l) has projecting from its rear face a stud 222 carrying a roll 224 which engages a xed cam 226 secured to the machine frame by a screw 228. The roll 224 is held against the cam 226 by a spring 239 connected at one end to a pin 262 carried by the finger 2|4 above its pivot 233 and at the other end to a pin 234 on the casting |24. When the shaft 82 is rocked to swing the applying roll |18 into operative position, the `roll 224 moves down the face of the cam 226 and, when it reaches a sharply inclined portion 236 of the cam face, the spring 23B causes the nger 2M to swing abruptly toward the strip S and press it against the applying roll |18. Thus, early in the movement of the applying roll the strip is pressed against the spurs with which the roll is provided.

During the movement of the applying roll |18 into operative position a compression spring 246 (Fig. 3) on the shaft 82 between the frame 30 and the lug 84 is allowed to expand to move the shaft 82 longitudinally to cause the face |90 of the slide |88 to press the marginal portion S of the strip against the inner face of the insole rib. The longitudinal movement of the shaft 82A is controlled by a cam piece 242 (Fig. 7) pivoted on the shaft 82 and adjustably held by a screw 244 to the rear face of the lever arm |22. The screw 244 passes through a slot in the cam piece 242 so that when the screw is loosened the cam piece may be adjusted about the shaft 82 to vary the location of a drop 246 on the cam piece with respect to a roll 248 mounted on a rod 259 which is threaded through the frame 36 and carries at its outer end a lock nut 252. The roll 248 initially engages a flat surface 254 on the cam piece 242 and prevents longitudinal rearward movement of the shaft 82 in response to pressure of the spring 240. When the applying roll approaches the operating position, however, movement of the cam piece has brought the drop 246 opposite the roll 248, allowing the shaft 62 to move rearwardly in response to the spring 248. The time of movement of the shaft 62 may be varied by adjusting the cam piece 242, as explained, and the initial position of the surface |98 of the slide |88 relatively to the work may be varied by turning the threaded rod 259 to adjust the roll 248 lengthwise of the shaft 82, this adjustment being desirable to accommodate insole ribs of different thickness.

To prevent the spurs on the applying roll |18 from engaging the lower feed roll 36 when no work is in the machine, rotation of the shaft 82 is limited in a counterclockwise direction by a stop screw 256 (Fig. 7) threaded through the frame 30 in position to be engaged by a projection 258 formed on the lever arm 22. l

The reinforcing strip S is led from a suitable reel (not shown) through a guide 269 (Fig. 8) on the upper end of an arm 262 of an angle lever pivoted at 264 to a plate 266 fastened to a bracket 268 secured to the frame 39. The guide 266 comprises two ears separated a distance equal at least to the width of the strip, the stripbeing held between the ears by a pin 218 passing through the ears of the guide. Opposite the pin 210 is a roll 212 mounted on a screw 214. From the guide 260 the strip passes through the guide- 210 and thelguide 2118i to the applying rolll I1-8f.1 The strip is prepared' for applicationtothe insole. bycoating one side of it first. with a thermo-l plastic stiifening material and then with latexE cement. Since the strip is coated with thermo. plastic stiffening material, it is desirable. totheat, it justbefore itsapplication to the insoletorender. it limp and hence in condition for convenient. application. Accordingly, as herein. shown, av relatively stationary heating element 211.6.;is.f`piv. oted. at, 218 to the plate 266. The elementY 21,6 is` urged against an eccentric screw 28 by a spring 282 connected at one end to theelement 216 above its pivot 218.and at the other endto. a pin 284 on the plate 266. By turning the screw 28B the position of the element 21,6Y about the pivot 213 may be varied. When the treadle is depressed toA bring the applying roll intooperative position, the stripguides 2 I0, 266 are moved toward the heating element 216 to present a length, of tape between them in a position parallel to the heating element and slightly spaced therefrom, the distance the strip is spaced from thegheatingelement being determinedV by Contact with the end of the guide 2li) with. the element at' one end and by engagement of the pin` 21.9 withthe element at the other. The guide. 2li). is, of: course, moved toward the heating element. by the counterclockwise rotation of the, shaft 82 and movement is imparted to the guide 26.0 from; the shaft 3,2 by an arm 28E secured to the shaftl and connected by a compressible link` to an arm 288 of the angle *lever pivoted at` 26.4. 'IlieVv link comprises a rod 298 which passes` through a hole in the arm 288-. and has. xed; thereto above the arm a collar 2,92 having; knifeedge contact with the arm 288V and below the; armisl ay similar loose collar 29.4. betweenwhich. and a fixed collar 296 on therod is a compression spring 298. It will be seen that as: the shaft 8.2 is4 rocked counterclockwise the arm` 2M; will: pushupwardly through the` spring 298; againstthe, arm 2&8 and move the arm.22 about the. pivot 264 to move the guide 260. toward the heating: element 216,- and4 at; the same time movement. of theA shaft will cause the guide 2li] to move toward the heating element'. After. contactv of the pin 210 of the guide 26@ with the heating.l element, further. movement of the rockshaft is permitted by'compression of the spring 238;. TheY position of theheating element maybe adjusted; by turning the screw 23% so ,that;the: guide 21H1;

will not engage the element until; tl'le. applying.v

roll; [18. has reached.Y its operative position sub'-` stantially in axialalinement with the feed roll.

In Fig. 8 the applying roll 11:8 is shown in its..` highest position as determined by a link SM1; piv` ot'ed to an arm 301| on the rockshaft; 8.2; and; carrying apinor roll 3 ii2jwhich, as. shownis' inengag e.

' ment with the deeper notch off a. rocking cam 304. Upon the next operation of-. the machine they roll 392 will engage the shallower notch of,` the cam 304 and arrest the applying roll |18 before it reaches. the position shown, this action and'- its purpose being more fully disclosed; in the patents` above' mentioned; I

After the applicationv of. the strip to one side;L of an; insole, for example from itstoe end, to theV breast line, the upper face offthe'insoleis'brought4 into, contact with a stop S` and the mechanism for severing the strip, no w tobe described, Will be operated. Y

Movement of the slide 31.4 With respecttothe plate 3&3 is limitedr by a screw studv 3.38i which. passesthrough a. slot 34); in the plate 368 and isthreaded: into. the slide 311.4'.

'llhestop 39.6. (Fig. 9') is formed. on thefront end.` of: a forwardly. and upwardly` inclinedl arm. 342 whichissecured by. screws 3M' tothe platel 08; the screws entering threadedholes 346 inhe plate. A latch plate 36S is. pivoted' to ears 32'20 upstanding from thev arm and the pivot pin is held in place by lugs 3.52- formed on a at spring secured to the arm. 352 at 356 and bearing againstA a square edge on the latch plate ito hold the plate yieldingly in horizontal position. When. the parts. are assembled, the head ofY the screw Swhich. holds the roll 32d on the blade. 32? projects upwardly beyond. the slot 330 andthe latch plate 3&8; lies over the screw head so that initialy the head engages a ledge on the underside ofthe latch plate, the ledge preventing closing ofi the shears untilthey. have reached operating position.

rEhe shearsare'operated by'an arm 36.9 (Fig. 7i) on arockshaft 3&2 the upper end'of the arm Stil' being connected to the operating slide 32B by a screw passing through thel arm and threaded intca hole Siin the operatingslide.

A- kneellever, lzispivoted'at tsrear. end to the columnv 22 andzat its front end is provided with a knee padSSD. Between its ends the lever 388; when swung to the operatorsvl'eft, will close the push, button, switch 3.84:. to supply current to the solenoid,y causing: the link` 311i. to be drawn down andthe arm EEO: to be swung forwardly, thus moving the operatingv slide 323 which, since the shearsv 355,V 3ri8.; are held from movement. by the ledge 35.8; on the latch 3115, causesV the slide 3M to move forwardly to carry the shears into operative positionl where the blades. embrace the strip/S. Whenthe bladeshavereached this po. sition, the headof the screw 326- is1forwardly beyondthe ledge 35%. ont the latch plate. 3.1582 and the shears1are then. closedi to sever the stripby .larg

furthermovementof the slide 328 relatively to the slide V3| 4, the inclined slot 339 then acting on the roll 324 to close the shear blades.

To prevent operation of the shear blades accidentally or otherwise when the applying roll is in operative position, means is provided to prevent operation of the lever 388 to close the switch when the treadle is depressed. The shaft 48 (Fig. 1) extends to the outside of the column 22 where it is provided with a short, forwardly eX- tending arm 332. Above the front end of the arm is a rod 334 guided for Vertical movement in lugs 396 formed on the column 22. The rod is held normally depressed by a spring 333 located on the rod between the upper lug 395 and a collar 40|) fixed to the rod. When the treadle is depressed, the arm 392 moves the rod upwardly, causing its upper end to enter a hole in the lever 388, thus preventing movement of the lever to close the switch while the tape-applying mechanism is in operation.

The plate 256 to which the heating element 213 is pivoted forms the bottom of a casing to which is hinged at 432 a side wall 4G4 which carries a front wall 436 having a side wall 408. The side wall 438 has a notch 4| i! to accommodate the lever 288 and a notch 4H.' to receive a projecting portion of the casting |14 and leads 4M for the heating element |16 when the cover plate 435 is 'swung about the hinges 402 to enclose the parts mounted on the plate 266. The top and bottom of the casing thus formed are left open.

, In the solenoid casing 28 is a distributing block 4| 6 from which the leads 4|4 for the heating element |13 are carried through a tube 4|3 and from which leads 420 are carried through a tube 422 to the heating element 216. The distributing block 4 6 is supplied with current by leads 424 from the same source of current as the leads 384 for the solenoid 378. When the head of the machine is lowered by telescoping the neck 24 in the column 722, the leads, which pass through the casing 28 to 4a junction box (not shown) at the base of the machine, will be festooned in the box without breaking any connections.

, Assuming the parts of the machine to be in the positions shown in Fig, 8, the toe end of an insole 'I having a rib R (Fig. 12) is placed between the rolls 36, 63 and the treadle |63 depressed. The downward pull on the rod i 32 caused by straightening the toggle |52, |55 turns the shaft 82 counterclockwise and swings the applying roll |13 into position in front of the feed roll SS, the reinforcing strip S being pressed against the feed roll by the finger 2M. Just as the applying roll |18 reaches operative position, the drop 246 of the cam 242 reaches the roll 248, permitting the spring 24|) to move the shaft 82 rearwardly and cause the face |93 on the slide |88 to force the upturned edge of the strip S against the inner face of the rib. At this point the screw 83 carried bythe arm 84 on the shaft 82 reaches the plunger and acts through the spring |32 to press the upper feed roll against the feather of the insole. The yielding connection |33 between the rods |23, then permits further depression of the treadle to cause the collar |34 (Fig l) to engage the spring 53 and operate the angle lever |53, lf2 to press the friction disk 44 against the pulley 45 which is being driven by the motor 5B. The feed rolls 33, 655 then begin to rotate and the reinforcing strip S is applied to the insole from the toe to the breast line, as shown in Fig. l2. When this point is reached the operator releases the treadle, holds the insole against the stop 3.36 and operates the knee pad 39|) to close the push button switch 384, causing the solenoid 3l'8 to pull down on the link 314 and operate the shears 35B, 323 to sever the strip.

When the treadle was released, the link 300 (Fig. 8) engaged the shallower notch in the cam 304 so that the applying roll could not swing to its highest position as shown in Fig. 8. Consequently, the portion of the strip S projecting beyond the guide 2|3 will be shorter than shown in Fig. 8, as is desirable in starting application of the strip at the breast line as is now done. By repetition ofthe operation, the reinforcing strip is applied to the second side of the insole from the breast line to the toe, whereupon the insole is again brought against the stop Sd, the strip severed and pressed against the end of the first strip applied by means of an inclined end face von the stop 333, the insole now being in the condition shown in Fig. 13.

The machine is arranged to be operated from either a standing or a sitting position. When standing, the operator will use the treadle |53 and may keep his heel on the treadle and rest his toe on a projection 433 on the base 23. When it is desired to operate the machine in a sitting position, the head with all the operating instrumentalities is lowered by loosening the clamp screws 26, the collars |43, |64 readjusted and a belt 46 of proper length provided. The operator may then sit on a stool or chair and utilize a treadle 432 which is pivoted at 434 rearwardly of the treadle |53 and has an upwardly extending arm 433 connected by a link 433 to the arm |53 at a point which is as far from the pivot |32 of the forward treadle as its rearward end is from the pivot 434. A toe rest 44d is provided for use with the treadle 432.

To register the number of pairs of insoles produced, a counter 442 (Fig. 3) is provided which is operated by a plunger 444, the arrangement being such that four oscillations of the plungerl are required to produce a change in the number indicated on the counter. The plunger 444 is connected by a link 443 to an ear 448 on the lever arm 33| (Fig. 8). Since this lever arm is operated four times in reinforcing each pair of insoles, the counter records the number of pairs of insoles treated.
